8config FEATURE_SHADOWPASSWDS
9  bool "Support for shadow passwords"
10  default n
11  help
12    Build support for shadow password in /etc/shadow.  This file is only
13    readable by root and thus the encrypted passwords are no longer
14    publicly readable.

16config USE_BB_SHADOW
17  bool "  Use busybox shadow password functions"
18  default y
19  depends on USE_BB_PWD_GRP && FEATURE_SHADOWPASSWDS
20  help
21      If you leave this disabled, busybox will use the system's shadow
22      password handling functions.  And if you are using the GNU C library
23      (glibc), you will then need to install the /etc/nsswitch.conf
24      configuration file and the required /lib/libnss_* libraries in
25      order for the shadow password functions to work.  This generally
26      makes your embedded system quite a bit larger.
27
28      Enabling this option will cause busybox to directly access the
29      system's /etc/shadow file when handling shadow passwords.  This
30      makes your system smaller and I will get fewer emails asking about
31      how glibc NSS works).  When this option is enabled, you will not be
32      able to use PAM to access shadow passwords from remote LDAP
33      password servers and whatnot.
34
35config USE_BB_PWD_GRP
36  bool "Use internal password and group functions rather than system functions"
37  default n
38  help
39      If you leave this disabled, busybox will use the system's password
40      and group functions.  And if you are using the GNU C library
41      (glibc), you will then need to install the /etc/nsswitch.conf
42      configuration file and the required /lib/libnss_* libraries in
43      order for the password and group functions to work.  This generally
44      makes your embedded system quite a bit larger.
45
46      Enabling this option will cause busybox to directly access the
47      system's /etc/password, /etc/group files (and your system will be
48      smaller, and I will get fewer emails asking about how glibc NSS
49      works).  When this option is enabled, you will not be able to use
50      PAM to access remote LDAP password servers and whatnot.  And if you
51      want hostname resolution to work with glibc, you still need the
52      /lib/libnss_* libraries.
53
54      If you enable this option, it will add about 1.5k to busybox.
